Just note that those *.wav files will have to be in the
correct format (44.1 kHz two-channel 16 bit) and maybe
require "byte order reversal" as well as stripping the
WAV headers to record them as a music CD. It seems that
some recording programs already contain this step. Refer
to audio CD specifications for why pure WAV files don't
make an audio CD.
